Flash floods hit Orchard, other parts of S'pore
-
Their mindset is as long as the basement of the towers is dry, they dun care whether the rest of the orchard road is flooded.
You wet, your busines.
But, Singapore have already water taxi in place to address the issue of transporation during ponding at orchard road.
Their findings is the floodgate did not fail as it stopped the water from flowing from the walkway to the basement but they did not look into the possibility of the channel being full and causing a backflow of the water into the basement.

they needed the extra water to float the water taxi scheme.

water taxi is a nice ideal.
but, i am taking my swim clothes and swim there.
cheap, better, slower

maybe fifi can amend the topic title to "Flash Ponds hit Orchard , other parts of S'pore"

The joke now is that they cannot even solve ponding, let alone flooding.
-
we could rear fish in the ponds and sell for cash

That is one way to help the bloody irresponsible government to minimize the disaster. Lick lick arse huh, nice job !!!!!

Chill lah, this most probably happens once in 142 years. This is not the once in 50 years thing.

Great idea.

when it overrains, it is bound to happen, why is that?
where is the greenery, ponds, lakes where the rain can seep thru? orchard road is man made structures, so where is the rain going to go to when the greenery disappeared.

Beause those stupid people done the wrong things like building flood barriers, raising the floor, etc.
No use de.
It's which side the swimming pool will be only.
Swimming pool on the road or swimming pool on the buildings' door way.

I look at the liat tower flooding pics and i lol when i saw the flood barriers up and water knee deep in the shops.

the shops located at liat towers ground floor should think of moving out to other places at orchard that does not have this problem. -
PUB should not have used the word "ponding": Balakrishnan
By Hetty Musfirah | Posted: 09 January 2012 1504 hrsSINGAPORE: The capacity of Stamford Canal will be increased by at least a third to reduce the risk of flooding along Singapore's shopping belt of Orchard Road.
Environment Minister Vivian Balakrishnan said in Parliament on Monday, that a consultancy study is underway and is expected to be completed by May.
He said such projects can be costly, but his ministry is prepared to undertake longer term investments.
But he cautioned that Singapore faces constraints.
Dr Balakrishnan said said: "I think many members will be familiar that whenever PUB has a drain, we have a drainage reserve.
"In other words, we always have space where if we need to deepen or widen a drain, we will take land from the owners or public utilities.
"Well in the case of Stamford Canal, which lies under Orchard Road, we've run out of drainage capacity. Secondly, to now embark on further surgery on Stamford Canal, would cost enormous disruption to services and the operations, pedestrian flow and vehicular flow along Orchard Road. I put all this because I want you all to understand that we are constrained."
The Stamford Canal starts upstream at the Botanic Gardens and Dempsey Hill, passes through Bras Basah and City Hall areas, before draining into the Marina Reservoir.
The area of special concern is a basin between Cuscaden and Cairnhill Roads at Orchard Road.
There have been three episodes of flooding in this area over the past eighteen months.
Dr Balakrishnan said the episodes are part of a larger pattern of rainfall change in Singapore over the past decades.
On 16 June 2010, some 100mm of rain fell in the area over two hours, causing Orchard Road between Cuscaden and Cairnhill Roads to flood to a depth of 300mm.
On 5 June 2011, some 124mm of rain fell over about four hours, and caused the Tanglin area to be flooded to a depth of 100mm.
Compared to the incidents on 16 June 2010 and 5 June 2011, the latest incident on 23 December 2011, saw the heaviest rainfall of 153 mm recorded over three hours.
Dr Balakrishnan noted that Orchard Road remained passable to traffic due to the completion of road raising works in June 2011.
But he noted that any form of flooding needs to be addressed.
Dr Balakrishnan said: "The technical difference between a flood, a flash flood and a pond - let me just say that as far as I'm concerned.
"PUB should not have used the word, "ponding".
"As far as I'm concerned, I call a spade a spade, a flood is a flood.
"As long as there is water accumulating somewhere, where it is not supposed to be, as long as it has implications on human safety, on business operations, that is a flood, that is a problem that needs to be resolved, PUB and the building owners must resolve it."
Dr Balakrishnan said PUB is evaluating various options.
This include storm water detention ponds in the upstream section, or a new canal to divert storm water from upstream portions of the catchment to the Singapore River.
Dr Balakrishnan said: "These detention ponds are not going to be cheap, to give you an idea of scale, they have a capacity of 40 to 50 Olympic sized pools.
"We will need land two to three times of a football pitch, putting aside land like that in a precious real estate in the Orchard Road area, I think members will agree, (it) is something we don't enter into likely.
"I set this very simple challenge to PUB. Let's us assume that we will continue to have storms, exactly similar to what we have in the last three episodes. In fact, let us assume further.
"Let us assume that it may be even worse than that. The reply that the engineers came back to me is, is that "if we want to able to be almost guaranteed that we can cope with similar storms of the last eighteen months, then in the long run we need to increase the capacity of Stamford Canal by 30 per cent."
Dr Balakrishnan said flood protection measures undertaken by building owners in Orchard Road over the past 18 months were generally effective, except for the basements of Liat Towers and Lucky Plaza that were overwhelmed by the heavy downpour on 23 December.
PUB is already working closely with the building owners at Liat Towers and Lucky Plaza to fine tune their flood protection measures, and review operating procedures.
Minister Vivian Balakrishnan has met the building owners of Liat Towers and Lucky Plaza, and is reassured that they will do their best to collaborate with PUB in resolving localised flooding problems."
Dr Balakrishnan said the panel of experts appointed middle of last year to review the overall drainage design and flood protection measures, is expected to complete its work by this week.
Their findings and recommendations will be shared with the public.- CNA

Upsizing Stamford Canal not best solution: expert panel
By Evelyn Choo/Tan Qiuyi | Posted: 10 January 2012 1515 hrs
SINGAPORE: The panel of experts appointed to review Singapore's flood protection measures submitted its report on Tuesday, after a six-month consultation period.
It proposed that national water agency PUB collect high-resolution data to get a better idea of Singapore's flood modelling profile, and the government look into new ways to tackle the surface runoff upstream rather than focus all efforts on the downstream.
The panel said a general widening of drains and canals in Singapore is not the best long-term solution for flood prevention. This holds true for the Stamford Canal which, the panel noted, had been designed to the standards in place at that time rather than standards more typical today.
It said the canal no longer has the capacity to drain away the volume of rainfall generated by storms like those in June 2010 and June 2011.
The panel does not believe that the whole-scale upsizing of the Stamford Canal is the best long-term solution to addressing flood risks on Orchard Road.
It suggested the government look into ways to store water in the Orchard Road area further upstream, such as through the use of roof tops, a water retention pond, storage tanks along the Stamford Canal's route to relieve its burden or a diversion canal to bring the water elsewhere.
New buildings should have water-retention roofs to make up for increased urbanisation and existing buildings should be retrofitted, said the panel.
Pavements could also be made porous to absorb some water and preventing all of it from rushing into canals, added the 12-member panel comprising local and international experts.
These measures control flooding at the source, said a member of the panel, Professor David Balmforth.
The panel acknowledged that these measures and the gathering of more accurate higher-resolution data on water drainage will require significant investment.
But Professor Balmforth, MWH UK's executive technical director, said: "What the experience in the rest of the world shows...is that the overall cost of doing it that way is generally significantly less than if you concentrate on trying to increase conveyance capacity all the time."
The panel said Singapore should also look into drainage systems that can deliver multiple benefits, for instance, water storage solutions that can serve as a source of water in times of drought.
The panel was appointed on June 30 last year to review drainage design and flood protection measures that will be implemented in Singapore over the next decade. It is chaired by Professor Chan Eng Soon, dean of the faculty of engineering at the National University of Singapore (NUS).-CNA

Another proof that Marina Barrage is the cause, that why it need to retain the water somewhere than diverting or upsizing Stamford Canal.
